Recommendations? I hope no one seriously believes that all of Europe is finishing apartments in gray-blue only.
The classic color choice of rooms depends on the lighting and the size of the rooms. If the windows face north, choose warm light colors - yellowish, beige, light green. To the south - dark blue, blue, burgundy, dark green, dark terracotta.
Embossed plaster or wallpaper designs in large rooms can be large, in small - small.
Light streams visually increase volume, dark streams decrease. You can play with color by covering metal parts (handles, loops, etc.) with chrome, nickel, bronze, copper, silver.
Previously, we were probably shy of bright colors, so our industry produced dull, gloomy colors and faded wallpapers. Now the choice of paints, varnishes, wallpaper, linkcrusts, linoleums, etc. so great that everyone can choose their own individual, style.
We will expand the rooms, make arched openings, plastered according to our own understanding, and replace the sanitary ware. We will paint our dwellings in bright or dull, warm or cold, cheerful or gloomy tones and “call” it a European-quality repair.
